86.5, and 265.6, and so we suspect there is a significant difference between the variances. This is confirmed by using Levene’s test (on the medians) since Levene(E20:G29,1) = 0.005478. Thus the normal one-way ANOVA is not the correct test to use. We employ Welch’s test instead,...
I know that I want to use the t test with unequal variances, and I know how to input this in excel if I had the actual sample points, but because the SD and mean etc are already calculated, how can I utilize Excel? Thanks! Charles Leah, 1. Yes, you can use...
SPSS reports the Levene3 test F ratio as part of the standard SPSS output for the independent-samples t test. If the p value for the Levene test is small (e.g., p < .01), this is evidence of possible violation of the homogeneity of variance assumption. (Note that when we test ...

Levene's test for equality of variances was used to ascertain the homogeneity of variance for the data, with significance set as p < 0.05. If data were found to be heterogeneous, the alpha level required for between-group significant interactions was adjusted to p < 0.01 to reduce the ...
Meta-analysis is a commonly used approach to increase the sample size for genome-wide association searches when individual studies are otherwise underpowered. Here, we present a meta-analysis procedure to estimate the heterogeneity of the quantitative tr
To determine parametricity, Levene's tests (homogeneity of variance) and S hapiro–Wilk (normal distribution) were employed. Where parametric assumptions were met, data were analyzed using a paired samples t-test to examine differences in Yo-Yo IR1 perfor- mance between conditions. A 2 ×...
